The utility has been battling to stabilise the national grid after a coal silo collapsed at the Majuba Power Station in Mpumalanga last month.

The power utility's Andrew Etzinger says maintenance work will be done but no load shedding is expected.

"We do a lot of maintenance over the next four days, in fact, over the next two weeks but that is not expected result in excessive pressure from the grid. So thank to South Africans for bearing with us."

The parastatal's Chief Executive Tshediso Matona last month warned South Africans that load shedding could become a reality for the next few months.

Government last week announced it would design and launch a procurement process to build 9,600 megawatts of nuclear power plants.
